Dr Naveen , my compliments to you  for raising this issue ,since very often we debate , but we hardly put any importance to multi-nutrient interaction while following the prescriptions of the integrated nutrient management .The divergent sources of nutrients are involved in , they are synergised  by one another ....Probably , the most ominous impact of such exercise is rendered by the congenial developments in soil micro-environment that play so pre-amptively, the  negative consequences of  nutrient interactions are kept at minimum. 

Dr Naveen, try to put the problem of private restrictions to address this issue.

Seeing  a very meak response , let me trigger some discussion on such an interesting topic. Do you feel , that the major  types of nutrient interactions will undergo some basic changes , regardless of nutrient management strategy .... 

For example, if High phosphate induced zinc non-availability operational under conventional fertilization programe,  will vanish under INM strategy..?

Agreed Dr Anoop, antagonistic effect of various nutrients when applied together is a major concern and poses a problem while preparing fortified fertilizers, as well optimization of the amounts as balanced dose is also a major concern.
